HAY-CARRIER.

Application led July 13, 1908. Serial No. 443,291.

To aZZ whom it may concern:

Be it known that I, F RANK S. POLLEY, a

citizen of the United States, residing atl fest Pullman, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Hay-Garriers, of which the following is a full, Clear, concise, and exact description, reference being had to the accompany-ing drawings, forming a part of this specification.

My invention relates to carriers, and has for its object the provision of improved means for controlling the load in transit.

My invention will be exhibited in the accompanying drawings, showing the preferred embodiment thereof, in which- Figure 1 is a side elevation of such preferred embodiment. Fig. 2 isan end elevation. Fig. 3 is a sectional elevation on line 3 3 of Fig. 2. Fig. LL is a plan view of the structure. Fig. 5 is a sectional View on line 5 o of Fig. 1. Fig. 6 is a detail view on line 6 6 of Fig. t.

Like parts are indicated by similar characters of reference throughout the different figures.

The wheeled carriage is of any suitable construction, the carriage shown including two parallel vertically disposed wheel supports or frame members a L that are integrally formed with outwardly extending flange plates ZJ Z) which are rigidly fastened to angle irons c c (see Fig. 3) The wheels Z are suitably mounted between the frame members a and are adapted to ride upon tread portions e c of an overhead track. One of the frame members a has slidable engagement with the angle irons c, so that the wheels upon one frame member may be adjusted with respect to the wheels upon the companion frame member to suit the width of the track over which the wheels are to run. To this end, the angle irons c may be provided with slots f disposed longitudinally thereof and bolts g passing through these slots and the flange portion b of the associate frame element a.

The structure thus far described constitutes the carriage provided for the purpose t of transferring the hay from place to place.

A swinging frame depends from the carriage, the carriage having two downwardly projecting bearings z', preferably integrally formed with the angle irons c, a shaft c,

preferably the shank of a bolt, being supported by said bearings, and, in turn, affording a pivotal support for the latter frame work, whereby said frame work is brought into swinging relation with the carriage. The frame work includes the two inverted members Z, the sleeves m intervening between the lower ends of the frame members Z and bolts n passing through the sleeves, which sleeves, together with said bolts, act as distance-preserving devices to maintain the lower ends of the frame members Z a proper distance apart. The sleeves m also serve to act as shafts upon which the rear sheave 0 and the forward sheave 29 may turn. The draft rope g, after being passed over the sheaves, has swivel connection at r with the carriage frame work, the other end of the draft rope being adapted for attachment to a draft animal or some mechanism for exerting pull upon the rope, it being preferable to direct the rope over the pulley p at an angle of about forty-five degrees to the horizontal, the rope passing over suitable guiding means for preserving this angle. It is to be understood that fork or sling pulley mechanism is provided to ride over the portion of the rope intervening between the rear pulley 0 and the place 1 of rope attachment.

The swinging frame work carries a member s of a rope clutch, this member being desirably fixed with respect to said frame work, and, in the embodiment of the invention shown, also constituting a distance piece between the upper portions of the frame elements Z. The carriage supports a clutch member t complemental to the clutch member s, the clutch member t being` pivotally mounted at its forward end upon the carriage structure, this mounting being located forward of t-he shaft Ze. The upper ends of links u are swingingly connected with the clutch member t at the rear of the pivotal connection of said clutch member with the carriage structure, the lower ends of said links having swinging connection with the frame work to the rear of the shaft Ze. The clutch members s and t have their opposing faces provided with curved recesses to afford a suitable passage through which the rope may travel between the clutch members.

The operation of the sheave and rope clutch mechanism thus far described is as so. that the rope may freely pass between said clutch members while lifting the load which is supported by the active pulley 0, the pulley 7) serving as a guide for the rope. Thus during all of the time that the rope is being pulled to lift the hay, the clutch members s and t are maintained in their separated relation, for the purpose which has been stated. l'Vhen draft upon the rope Q ceases, the load carried by they rope swings the frame work in a counter-clockwise di- Y rection, this tendency being exerted by reason of the engagement of the said rope with the pulley 0. rlhe links u are thereupon drawn downwardly, whereby the clutch member t is forcibly engaged with the rope g by the load of hay, which thus acts to prevent its own descent. Vlien the hay has been raised to a suitable elevation, the draft rope may be uncoupled from the animal or the means by Vwhich the rope is pulled, whereafter the shifting ropes o attached to the carriage, may be pulled to move the carriage along its track, thereby to shift the sheave mechanism and the load of hay it carries to the place where the hay is to be deposited, the hay then being released by tripping the sling or fork mechanism, as is well understood by those familiar with the art. It may be desired on occasion to lower the hay as it is being moved to the place of deposit; for instance, to clear beams. This temporary lowering of the load in transit is accomplished by momentary separation of the clutch member t from the clutch member s, which momentary separation may be conveniently brought about by the elevation of the rear end of the clutch member t, which elevation is desirably accomplished by means of a pull exerted upon the free end of a trip rope w which passes over a pulley and is connected at its other end to a rearward extension of the clutch member t. The trip rope w may also be pulled to separate the clutch member t from the clutch member s when the rope is to be pulled down over the sheave o, for the purpose of returning the fork or sling pulleys to the wagon from which the hay is being unloaded.

The portions of the clutch members s and t which margin the curved recesses therein are desirably toothed, the teeth upon one clutch member being adapted to mesh with the teeth upon another clutch member when the draft rope has been worn sufiiciently thin. The purpose of providing these teeth is to enable a contraction of the rope passage atl'orded by the clutch members while at VThe distance between the axis of the shaft 'la and the aXis about which the Vclutch member t moves, is preferably equal to the distance between the pivotal axes at the ends of the linksu, whereby the clutch member t isV always maintained in parallel relation with the clutch member s. In this way a very long rope-gripping surface is afforded, whpreby the rope may be firmly held without being crimped. Y

In the preferred embodiment of the invention, the plane of rotation of the sheavesV 0 p is transverse to the line of travel of the carriage, whereby pull may be exerted upon the draft rope without causing the travel of the carriage upon its track.

l/Vhile I have herein shown and particularly described the preferred embodiment of my invention, I do not wish to be limited to the precise construction shown, as changes may readily be made without departing from the spirit of the invention.

Having thus described the preferred embodiment of my invention, I claim as new and ldesire to secure by Letters Patent the following 1. In a carrier, the combination with a carriage, of a draft rope for lifting the load, a pair of draft Vrope engaging sheaves, a frame work for said sheaves having swinging mounting upon the carriage at a location between said sheaves, the parts being so re-y lated that the draft rope swings the frame work in one direction when pull is exerted thereon to lift the load, and swings the frame work in the opposite direction when the elevated load is relieved of lifting force, a draft rope clutch between whose members the rope may travel, one clutch member being carried by the sheave frame work, the

other clutch member being swingingly connected at one end with the carriage, and link mechanism connecting the latter clutch member with the swinging frame work, whereby the frame work causes separation of the clutch members when the load is being lifted and a closing movement of the clutch when the elevated load is relieved of lifting force,VV

the distance between the axes of movement of the frame work and the swinging clutch c member being substantially equal to the distance between the points of union of the link mechanism with the frame work and swinging clutch member, whereby the gripping surfaces of the clutch members are maintained in substantially parallel relation throughout the relative movements of the clutch members.

2. In a carrier, the combination with a carriage, of a draft rope for lifting the load, a pair of draft rope engaging sheaves, a framework for said sheaves having swinging mounting upon the carriage at a location between said sheaves, the parts being so related that the draft rope swings the frame work in one direction when pull is exerted thereon to lift the load, and swings the frame work in the opposite direction when the elevated load is relieved of lifting force, a draft rope clutch between whose members the rope may travel, one clutch member being carried by the sheave frame work, the other clutch member being swingingly connected at one end with the carriage, and link mechanism connecting the latter clutch member with the swinging frame work, whereby the frame work causes separation of the clutch members when the load is being lifted and a closing movement of the clutch when the elevated load is relieved of lifting force.

3. In a carrier, the combination with a carriage, of a draft rope for lifting the load, a pair of draft rope engaging sheaves, a frame work for said sheaves having swinging mounting upon the carriage at a location between said sheaves, the parts being so related that the draft rope swings the frame work in one direction when pull is exerted thereon to lift the load, and swings the frame work in the opposite direction when the elevated load is relieved of lifting force, a draft rope clutch between whose members the rope may travel, one clutch member being carried by the sheave frame work and the other by the carriage, and a connection between said frame work and the latter clutch member, whereby the frame work causes separation of the clutch members when the load is being lifted and a closing movement of the clutch when the elevated load is relieved of lifting force.

4. In a carrier, the combination with a carriage, of a draft rope for lifting the load, a sheave structure swingingly mounted upon the carriage and serving to be moved by said rope in one direction when the load is being lifted and serving to be moved in the reverse direction by the elevated load when relieved of lifting force, a draft rope clutch having one member provided upon the frame work and the companion member mounted upon the carriage, and a connection intervening between the frame work and the latter clutch member, whereby when theframe work is moved by the rope when the rope is pulled to lift the load, the clutch members will be separated, and whereby when the said frame work is moved reversely, when the elevated load is relieved of lifting force, closing movement of the clutch is effected.

5. In a carrier, the combination with a carriage, of a draft rope for lifting the load,

a sheave structure carrying a sheave overV which the rope passes in leaving the carrier, said sheave structure being swingingly mounted upon the carriage and serving to be moved by said rope in one direction when the load is being lifted, and serving to be moved in the reverse direction by the elevated load when relieved of lifting force, and a draft rope clutch brought into braking engagement with said rope by the frame work when the frame work is moved by the elevated load upon the removal of lifting force from the load, and released from braking engagement with the rope when the frame work is moved as a consequence of pull thereupon to lift the load.

6. In a carrier, the combination with a carriage, of a draft rope for lifting the load, a sheavestructure carrying a sheave over which the rope passes in leaving the carrier, said sheave structure being movably mounted upon the carriage and serving to be moved by said rope in one direction when the load is being lifted, and serving to be moved in the reverse direction by the ele vated load when relieved of lifting force, and a draft rope clutch brought into braking engagement with said rope by the frame work when the frame work is moved by the elevated load upon the removal of lifting force from the load, and released from braking engagement with the rope when the frame work is moved as a consequence of pull thereupon to lift the load.

In witness whereof, I hereunto subscribe my name this 11th day of July A. D., 1908.
